Description

Virtual network operator management method

Technical Field

The invention relates to the field of satellite communication, in particular to a virtual network operator management method.

Background

Currently, as the data capacity of high-throughput satellite systems increases, so too does the satellite communication services that they can provide to users. However, the investment of the satellite communication system in the early stage is huge, and the threshold is high, so that on one hand, the main operators of the satellite communication system are difficult to quickly pass through commercial popularization service to terminal users, and the cost is difficult to be quickly recovered and the profit is difficult to obtain; on the other hand, many smaller-scale operators have strong market popularization and willingness to expand satellite communication internet service market, but cannot enter into the line of satellite communication operation due to huge investment of funds.

Typically, a conventional satellite network communication system service includes a satellite network provider and satellite network subscribers to which the network communication service is applied. Wherein the satellite network provider has all devices including gateway stations, remote devices and associated software to charge its network users for providing communication network services.

In conventional business models, it is difficult to incrementally add and extend resource functionality for new users. For example, to create a new independently managed dedicated satellite network, operators must obtain, install, configure, add and manage at least one new modem chassis and modem board card and transponder and network segment parameter configurations.

Moreover, different operators cannot distinguish and manage their own resources such as baseband, satellite, terminal, etc. in the same set of network management system.

At the same time, the customer cannot independently utilize all network functions, and needs to coordinate control of these functions with third party network operators, thereby increasing costs and reducing customer flexibility and autonomy. In order to have flexible control over these network parameters, each user is required to spend additional money to build an independent network, dedicated to their application, and to adjust to their needs.

In addition, each satellite communication system manufacturer has a sophisticated network management system, and if a new system is to be redesigned and developed, the cost will be greatly increased.

In summary, a high-throughput satellite communication system with a large bandwidth and supporting more terminals is very inconvenient when it is operated together for multiple operators.

in S130, the management rights allocated to the roles of the exclusive virtual network operator include at least one of multicast upgrade rights of the terminal, configuration and monitoring rights of the network segment, addition, deletion and remote configuration rights of the terminal, and one exclusive virtual network operator user may allocate different rights to multiple roles of the exclusive virtual network operator;

in S150, management groups are created according to the attributes of the end users, so that all the end users in each management group have at least one set of the same attributes.

Further, in S200, managing the exclusive virtual network operator includes:

the exclusive virtual network operator user manages respective end users within respective rights, including management of private network segments, satellite virtual resource networks, and management groups.

Further, in the step S100, creating the shared virtual network operator includes:

s121, adding a cloud resource management module;

Detailed Description

The description of the embodiments of this specification should be taken in conjunction with the accompanying drawings, which are a complete description of the embodiments. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated simply or conveniently. Furthermore, portions of the structures in the drawings will be described in terms of separate descriptions, and it should be noted that elements not shown or described in the drawings are in a form known to those of ordinary skill in the art.

Any references to directions and orientations in the description of the embodiments herein are for convenience only and should not be construed as limiting the scope of the invention in any way. The following description of the preferred embodiments will refer to combinations of features, which may be present alone or in combination, and the invention is not particularly limited to the preferred embodiments. The scope of the invention is defined by the claims.

In an embodiment of the invention, it involves including a primary network operator (Host Network Opertor, HNO), a virtual network operator (Virtual Nework Operator, VNO), and a VSAT end user.

1. Main network operator

The system is provided with the responsibility of complex infrastructure construction and maintenance, and he is usually in possession of or leased with satellite resources, while the responsibility of purchasing and maintaining satellite ground equipment in the satellite network includes hardware and software, such as: baseband modem cards, baseband chassis, network controllers, network management systems and servers, switches, master station antenna assemblies, master station Radio Frequency Transceivers (RFTs) or radio frequency/intermediate frequency converters (IF/RF converters), and the like. The HNO is responsible for the expansion of the space resources of the satellite network, he can create new satellite communication channels and manage the shared devices to allocate network resources to the VNO, he can provide satellite network management, installation and maintenance, remote debugging support, link budget preparation, master device maintenance, upstream Internet connection/dedicated data connection maintenance and software firmware upgrade coordination for the VNO users. The HNO can comprehensively grasp the operation states of the whole satellite network and all terminals, and the resources of all VNOs and the use states of the terminals by using the network management system.

HNO is responsible for managing parameters of the overall system including outbound carrier, bandwidth, carrier frequency, power, ACM adaptive control modulation and coding parameters, qoS policies, and configuration of the master station modem, NMS client and server, internet Protocol (IP) address of the network controller, and switches or routers, etc.

HNOs receive revenue from space segment operations, hosting services, and charging VNOs for network management fees. Network management costs include, for example, lease modem card costs, debug, configuration management, real-time monitoring, and periodic report generation costs. HNO charges the VNO for renting the modem card by charging the VNO for Mbps (exclusive VNO) or MHZ (shared VNO).

2. Virtual network operator

A satellite network operator based on "non-infrastructure" under satellite network services provided by a business model of a primary network operator (HNO). VNOs are a low cost method of entering satellite network operations because the system has made a lot of early capital investment and the VNOs can step up system functions as business opportunities grow. Furthermore, the VNO traffic model may better control the end user network, thereby providing better customer service.

The VNOs are classified into an exclusive VNO (Dedicate VNO) supporting an independent network management mode (resource independent management and expansion) and a shared VNO (Shared VNO) supporting a shared network management mode (resource system dynamic deployment) according to the network management modes.

(1) Exclusive VNO users:

one or more independent satellite communication channels may be managed, the VNO being responsible for managing and maintaining a part of the hardware and software in the satellite network, e.g. a modem board, the VNO being responsible for maintaining software or firmware upgrades of the leased modem channels (by coordinating with HNO if necessary), rebooting, alerting and status monitoring, modem board extension installation (by coordinating with HNO if necessary), commissioning of new remote sites and support for all network user sites, network user configuration, user IP address allocation (by coordinating with HNO if necessary), entry and exit slots and frequency planning, terminal remote management, monitoring, maintenance etc.

(2) Sharing VNO users:

revenue is constantly obtained from the user segment retail terminals and from providing network infrastructure services, terminal equipment installation and maintenance services, software upgrade services, terminal value added services, etc. to the end users of the satellite network. Each high-throughput satellite network user can be managed by a respective VNO in a shared high-throughput satellite network to provide services, such as internet access service, data and video broadcast services, and other IP business services, for the user, and the satellite network user obtains technical support such as terminal access, qoS quality of service configuration when bandwidth is insufficient, and the like through the VNO.

3. VSAT end user

The satellite communication system access and IP service are obtained by purchasing the VSAT terminal and antenna radio frequency, VSAT installation service, internet access service, traffic package service, etc. from the VNO. The VSAT terminal may be a fixed station, an onboard station, or a piggyback station. The user can access the satellite communication system anytime and anywhere, and the bandwidth and condition of the access of the VSAT terminal are managed and monitored by the VNO virtual operator.

1-3 are schematic flow diagrams of a virtual network operator management method according to an embodiment of the present invention, where the virtual network operator management method includes:

and S200, managing the exclusive type virtual network operator and/or the shared type virtual network operator.

Wherein in the step S100, creating the exclusive virtual network operator includes:

Wherein, in S200, managing the exclusive type virtual network operator includes:

Wherein in S100, creating the shared virtual network operator includes:

s121, adding a cloud resource management module;

Wherein, in S200, managing the shared virtual network operator includes:

The following describes a virtual network operator management method according to an embodiment of the present invention in detail with reference to a satellite communication network system:

as shown in fig. 4, a conventional satellite network communication system includes a gateway station baseband 42, a gateway station radio frequency 43 (including intermediate frequency and radio frequency) for performing communication with a satellite 44 via an internet protocol IP network 41, and a VSAT terminal 45 and the following devices for performing transmission of service data. In addition, network operators 47 of a main network operator (HNO), a Virtual Network Operator (VNO), perform satellite network monitoring management and maintenance management functions for baseband equipment through the satellite network management system 46.

As shown in fig. 5, the gateway station baseband 42 includes a network controller 420, a baseband chassis, a modulator 421, a demodulator 422, a combiner matrix 423, a splitter matrix 424, and a switch board (not shown). The logic channels of the baseband modem board (modulator 421 and demodulator 422) are connected to the network controller 420 through a switch board (not shown in the figure), management of satellite channels and service transmission are completed through interaction of signaling and service data, the radio frequency transmitting port of the modem board of the modulator 421 is connected to the combining matrix 423 of the chassis, the radio frequency receiving port of the demodulator board of the demodulator 422 is connected to the branching matrix 424 of the chassis, and thus the modulator 421 and the demodulator 422 are both connected to the gateway station radio frequency 43 through matrix outlets. HNOs may lease modulation or demodulation channels of one or more baseband chassis within different baseband chassis to an exclusive VNO via satellite network management system 46 (see fig. 4). The leased channel or baseband board, exclusive VNO users can manage the physical channel by themselves.

As shown in fig. 6, an exclusive VNO user (i.e., an administrator of the VNO) 442 has an exclusive type VNO role 443 that has an exclusive type SVN (satellite virtual network) 431. An exclusive type of SVN (satellite virtual network) includes a modem channel to which the HNO leases to an exclusive VNO, and dedicated NS (network segments) 434 and 435 assigned to the exclusive VNO by the HNO or created by the exclusive VNO itself. The dedicated NS is composed of an outbound link and a plurality of inbound links and can only be allocated by a management group of exclusive VNO type users, the channel resources are respectively associated with a modem channel, and the radio frequency port is finally connected with the gateway station radio frequency 43. The network management system can ensure that only the exclusive VNO type VSAT terminal can access the channel after the dedicated NS is enabled. The management groups 436,437 are a collection of terminals having VSATs of the same IP network configuration, and the management groups 436,437 typically also have the same territory, such as a province, or the same user, such as a company, VSAT terminal users are all managed in the same management group. Different exclusive VNOs have different users, VNO roles, SVNs, dedicated NS, management groups, IP networks, and modem channels, so that the system realizes resource isolation from the physical layer and the network layer, and ensures that the VNO users are mutually independent in use and management of resources.

The method of monopolizing VNOs can avoid that each user is not allowed to customize a single network for their specific application (e.g., VOIP, web browsing, etc.), the client cannot independently utilize all network functions, and the control of these functions needs to be coordinated with a third party network operator, which reduces the flexibility and autonomy of the client. In order to flexibly control these network parameters, each VNO user using the method of exclusive VNO can lease a baseband channel to establish a user independent network, dedicated to their application, and freely adjusted according to their needs.

As shown in fig. 7, all of the shared VNOs may share the same modems and

channels

421 and 422, and share the same split and combined

matrices

423 and 424 and are connected to the gateway station radio frequency 43. The network controller 420 (the number may be multiple) of the system may be used in the same gateway station in association with the baseband modem and its channels across the chassis through ethernet, where the network controller may dynamically allocate resources for all VSAT terminals in the managed network segment according to the superframe period in the system, but the system cannot allocate resources for VSAT terminals of VNO users across multiple network controllers, so the system needs to have a cloud resource management module 425 network element to implement the above functions. The cloud resource management module 425 completes resource allocation condition acquisition for all network controls in every 32 superframe periods by establishing connection with the network controller, dynamically allocates bandwidth resources under a plurality of network controls based on the Maximum Information Rate (MIR) and the Committed Information Rate (CIR) of the shared VNO and the maximum information rate and the committed information rate of the VNO under different beams, and completes dynamic adjustment of resources immediately in the next superframe period after the network control receives an instruction of the cloud resource management center.

As shown in fig. 8, a shared VNO user (i.e., an administrator of the VNO) 441 has an exclusive type VNO role 440 that has a shared type SVN (satellite virtual network) 431. All the shared SVN satellite virtual networks 449 may use the shared NS network segment 448 together, and the cloud resource management module 425 obtains the resource allocation situation of the network controller 420 for different VNOs in the shared network segment 448 in real time, and dynamically adjusts the sum of the maximum real-time rate and the guaranteed rate of all the terminals under different VNOs in real time according to the maximum information rate and the guaranteed rate configured by each shared type of SVN (satellite virtual network). The shared NS network segment 448 is created by HNO only and consists of an outbound link and a plurality of inbound links, channel resources associated with the modem channels 451 respectively, and the radio ports ultimately connected to the gateway station radio 43.

One shared type of SVN is the same as an exclusive type of SVN, and multiple management groups can be created and associated. A management group is a collection of terminals that have VSATs of the same IP network configuration, and typically the same territory as a province or the same user as a company's VSAT terminal users will all be managed in the same management group. Different shared VNOs have different users, VNO roles, SVNs, management groups, IP networks, but the same shared NS, modem channels may be used. Because the shared VNO resources, especially hardware channels, are shared, they are easy to manage and expand.

As shown in fig. 9, the VSAT terminal 45 users of the satellite network 1 include, in addition to the VSAT terminal device 112, a plurality of end users 116 connected to the associated VSAT terminal device 112 via a communication connection, and the end users 116 may be user computers or mobile devices such as notebook computers or smartphones.

The VSAT terminal device 112 and the end user 116 can communicate with the terminal device 112 via a dedicated communication link 113, which can include an RS-232 data link or other point-to-point communication link, as can multiple user computers 116 using a multi-point communication link, such as an ethernet data link. In addition, multiple user computers 112 may communicate with the network 1 through a single VSAT terminal 112 using wireless communication links 115. The wireless communication link 115 may use a radio network such as Wifi or Wimax, an optical network, a microwave link, or other wireless communication link.

As shown in fig. 10, each end user transmits communication data from a remote user to an upstream user using a shared network device VSAT end device 112, and each remote terminal receives communication data from the upstream user transmitted via the shared network device. The end virtual router 122 appends the virtual router's VLAN tag to each IP packet to be sent to the upstream user based on the contents of the end virtual router tag table 123. The virtual router labels contain a unique identifier that can be differentiated by service or user, mapped to the local IP address of the remote user or upstream user, and the mapping between the virtual router labels and each local IP address is stored in the terminal virtual router label table 123. Further, based on the contents of the end virtual router label table 908, when the end virtual router removes the virtual router label from each communication packet transmitted to the remote user, and routes the packet to the remote user's local IP address.

As shown in fig. 11, the network controller 420 includes an outbound virtual router 132 connected to the IP network 41, and a protocol converter 134 connected to the gateway station baseband 42. The protocol converter 134 converts the communication service data from the modem board in the chassis of the gateway station from the satellite communication protocol to the IP network protocol, transmits the communication service data to the IP network after passing through the core switch, converts the communication service data from the IP network to a protocol suitable for satellite communication, transmits the communication service data to the modem in the baseband chassis in the gateway station, and then forwards the communication service data to the baseband radio frequency 42 of the gateway station. The outbound virtual router 132 adds a virtual router tag to each communication packet to be sent to the remote user on a particular VLAN based on the contents of the outbound virtual router tag table 133. The virtual router labels include unique identifiers that are mapped to local IP addresses of the remote user or upstream user, and the mapping between the virtual router labels and each local IP address is stored in the outbound virtual router label table 133. The outbound virtual router 132 then removes the virtual router label from each packet to be sent to the upstream user and routes the packet to the upstream user's local IP address based on the contents of the outbound virtual router label table 133.

Communications between the network controller 420 and the remote terminal according to an embodiment of the present invention include a virtual router function that repackages IP packets into virtual router packets by adding virtual router labels. Each intermediate element (including gateway modem chassis, satellite intermediate frequency radio frequency converter/satellite) is configured to pass data packets containing virtual routing tags. At the network controller side, the virtual router data packet is converted back to an IP data packet by consulting the virtual routing label, and the table maps the combined virtual router address and IP address back to an IP address. Also, on the VSAT terminal side, the outbound virtual router packets are converted back into IP packets using the virtual routing table.

Such a design has the feature of being entirely free in the management of satellite communication networks, both in software operators and in hardware operators. One virtual network operator may select and assign an IP address for a user of its network 1 without having to consider or know any IP address selected by other virtual operators for its users. For example, network operator a may assign an IP address of 10.0.0.1 to a network a remote user, while network operator B may also assign the same IP address of 10.0.0.1 to a network B remote user, without any risk of collision.

According to the virtual network operator management method provided by the embodiment of the invention, an administrator creates different virtual operator roles according to different requirements through a network management system, and each type of virtual operator roles has part of management authority of the network management system. Such as an administrator may assign user leased modem communication channels to the exclusive virtual operator roles so that the exclusive virtual operator may itself lease and configure parameters such as satellite bandwidth and create independent satellite communication subnets on the network management system.

The authority of the network management system management roles includes management authorities of various resources of the communication system, for example, a common modem board card, a network controller, a baseband chassis and a receiving and transmitting matrix among virtual operators, a VSAT terminal, a management group, an outbound channel resource, an upgrade file, map configuration and viewing, and the like. The network management system supports different configurations of the visibility of the virtual operator management providing network resource levels, the system limiting that each operator can only manage the resources that are individually visible, e.g. terminals, communication channels and subnets managed between different virtual operators are all mutually invisible.

A virtual operator can be created to bind a plurality of user accounts into a virtual operator role, the virtual network operator can access the network management system through a Web browser without downloading a local client, and the creation, deletion and configuration of a satellite communication sub-network, such as frequency points, super frame planning, transmitting power, symbol rate and the like, and ACM (adaptive control modulation coding) for configuring the communication channel, the working state of the satellite communication channel, the management group for managing the virtual operator and the network address pool planning thereof, the remote upgrading and control of a terminal, the state monitoring and the like can be realized.

The network management system may be configured to perform a primary network operator function or a virtual network operator function. The network management system is configured to provide different levels of capabilities for different users. A Network Management System (NMS) may provide different levels of permissions and visibility for network resources depending on the type of user. For example, a master network operator user type identified as a master network operator (HNO) super user has the right and visibility for all communication system resources, a network operator type identified as a Virtual Network Operator (VNO) super user has only partial resource visibility, a "network manager" type of a shared, independently managed network in the communication system, and a network operator user type identified as a "VNO guest user" has only read-only right, configuration parameters and network status of a network of a virtual satellite network SVN in the communication system can be observed.

The network management system may create the capability of other user types with other rights and network resource visibility. For example, one VNO account may be configured to provide access to only the resources allocated to the network of the VNO. The network management system may also configure a VNO account for NMS users of each VNO, including user information such as name/password, user type (e.g., VNO superuser or VNO guest, shared VNO, or exclusive VNO). The VNO super-user may perform virtual network operations using the network management system, e.g., add, modify, and delete network remote users, activate and deactivate network remote users, select quality of service (QoS) profiles, monitor and query for remote statistics, and have visibility to the network it manages. The VNO super-user cannot add or modify the operator, independently add or modify hardware such as a modem board or a network controller, or view other shared networks in the communication system, and these operations affect network configuration of other users, and only remain for the HNO and the account used by the system network administrator. The configuration and monitoring capabilities of the different types of VNOs are shown in the following table.

As shown in fig. 12, the principle of how to add and manage exclusive virtual network operators as in steps S111-S115, S200 is shown in detail, including:

first, HNO adds or modifies one or more network segments to a private network segment under a beam interface in a network management system. A private network segment can only be used by one VNO role and cannot be shared among multiple VNOs. When the private network segment is created, a modulation channel or a plurality of demodulation channels are associated, and when the private network segment is allocated to the SVN of an exclusive VNO, the modulation or demodulation channels of the private network segment are automatically allocated to the exclusive VNO, and the VNO will have the capabilities of monitoring, configuring, upgrading (if necessary, by negotiating with the HNO) the channels, etc. (the relevant rights still need to be allocated in the third step).

In the second step, HNO adds an SVN of the exclusive VNO type to the network management system, and may allocate one or more private network segments to the SVN. The management group or terminal created by the exclusive VNO user under the SVN can only use a part or all of the private network segments allocated to the SVN.

And thirdly, HNO can add one or more exclusive type VNO roles in a role management interface of the network management system, and allocate authority and SVNs of the exclusive type VNO for the roles. The network management system may choose to provide recommended default permissions for different types of VNO roles, for example: the terminal multicast upgrade authority, the network segment configuration and monitoring authority, the terminal adding, deleting, remote configuration authority and the like; the HNO may create VNO roles with different rights for one operator, for example, VNO role 1 has the rights to configure the private network segment and modify the terminal, and VNO role 2 can only view the private network segment and view the terminal, so that the same VNO operator may be used for users with guest rights and different user access systems with administrator rights.

And fourthly, adding one or more users in a user management interface of the network management system by the HNO, setting login names, passwords and distributing roles of the VNOs for the users.

And fifthly, the VNO user logs in the network management system through the Web browser by using the account number.

Sixth, the VNO user creates one or more management groups, where the terminals in the same management group are a group of terminals with the same attribute, such as the same network access location or beam resource of the terminal, and the terminals belong to a region or company unit.

Seventh, the VNO user configures a user address pool for the management group (negotiating with HNO is required if necessary).

Eighth step, the VNO user creates, deletes, modifies, configures, remotely maintains and monitors the VSAT terminal, and the VSAT terminal managed by the VNO user is limited to the present VNO.

And ninth, the VNO user can configure and monitor the dedicated network segment of the VNO, modify, e.g., frequency point, symbol rate, output power, superframe plan, etc., and monitor and maintain the modem channel of the VNO.

The SVN (satellite virtual resource network) of the VNO is created and configured, and the maximum speed limit and the minimum guaranteed speed of the VNO entry and exit resources can be configured according to the resource pool of the beam.

The HNO configures the authority of the VNO, creates a VNO role, and binds SVN resources with the VNO role. Multiple VNO accounts may be created to bind with the VNO role, such that the same virtual operator has multiple access accounts on the network manager.

As shown in fig. 13, the principle of how to add and manage the shared virtual network operators as in steps S121-S125, S200 is shown in detail, including:

the flow of shared VNO creation is basically the same as exclusive VNO, the main difference being:

(1) The system needs to add RMC (cloud resource management center) to realize the function of sharing the VNO;

(2) When creating the shared VNO, the system allocates not a dedicated network segment, but the total MIR and CIR and the MIR and CIR of the VNO user in each beam;

(3) The shared VNO monitors information such as real-time throughput of SVN and management group of the VNO, and the exclusive VNO monitors parameters such as throughput of the private network segment;

(4) The shared VNO supports the functionality of adding a secondary shared VNO.

In summary, the virtual network operator management method of the embodiment of the present invention provides two management modes of the virtual operators, namely, the exclusive mode and the shared mode, so that different configuration management modes can be provided for operators with different operation management requirements.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
